Unless specified by manufacturer instructions, what gauge of copper should be used to bond natural gas piping?

The correct gauge of copper wire to be used for bonding natural gas piping, unless specified otherwise by the manufacturer, is 6 A.W.G. This gauge ensures adequate conductivity and safety for grounding and bonding applications, which are critical when dealing with gas piping systems. Proper bonding helps to prevent the buildup of stray currents that could pose a risk of electric shock or fire.

Using a gauge that is too thin may lead to increased resistance, which can affect the performance of the bonding and increase the risk of potential hazards. Thus, 6 A.W.G is the recommended standard for ensuring effective grounding and bonding, maintaining both safety and compliance with electrical codes and best practices.
